Audio problems on iBook2 (Gnome2.2/Totem)

[Stefano Barale <stefano@ormae.com>]

Hi everybody,
seems I've gone a little bit further in the understanding of my audio
problem (totem not playing audio, while vlc and xmms seem to work fine).
Running totem from console I get:
(totem:440): Gdk-WARNING **: locale not supported by Xlib
 
(totem:440): Gdk-WARNING **: can not set locale modifiers
 
(totem:440): GnomeUI-WARNING **: While connecting to session manager:
Authentication Rejected, reason : None of the authentication protocols
specified are supported and host-based authentication failed.
audio_oss_out: switching the soundcard to 16 bits mode failed
audio_esd_out: connecting to esd server...
audio_esd_out: can't connect to <default> ESD server: No such file or
directory
load_plugins: audio output auto-probing didn't find any usable audio
driver.

Anyone met the problem before? 
As I told before xmms works fine (apparently with audio_oss), even if
I'm still experiencing the awful "no-cdaudio" problem (even if I set all
the right permissions for /dev/dsp, /dev/mixer, etc and installed
xmms-cdread.
I'm using Debian testing/unstable with kernel 2.4.18-newpmac (which I
suppose I will have to upgrade to Benh to get 3d acceleration working). 
My machine is an iBook2 500Mhz but:
less /proc/cpuinfo says:

Apparently no sound card in /proc/pci:
